Answer:
480 Boy
Step-by-step explanation:
The ratio of Boys = 4x
The ratio of Girls = 5x
The Number of Boys in the School = 4x + 5x = 1080
= 9x = 1080
= x = 1080/9
= x = 120
The ratio of Boys = 4x = 4 x 120 = 480
The ratio of Girls = 5x = 5 x 120 = 600
Hence, Number of Boys = 480
Ratio Boys to Girls = 480:600
